I have a pretty old Acer aspire from 2011 and I have connected my 5.1 receiver to it but the sound cuts out for a second all the time. It happens completely randomly and I'm running out of ideas. I have tried googling the issue and tried almost everything without any luck. For example I reinstalled the drivers, swapped ram, stress tested to see if it's related to high cpu usage, checked the cables, changed output format etc. There is no problems at all when I have my ps3 connected to it so it shouldn't be the receiver. This problems only happens with the digital output, headphone jack is fine. Any suggestions?
Edit: Seems it cuts out way more when watching a movie. The cpu usage is usually at 100% then. But the problem is still there even with low cpu usage.
